pci: implement "pci=noaer"
For cases in which CONFIG_PCIEAER=y (such as distro kernels), allow users to disable PCIE Advanced Error Reporting by using "pci=noaer" on the kernel command line. This can be used to work around hardware or (kernel) software problems. Signed-off-by: Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
